The opposite of Firsties. A comment so out of place or terrible that it ends the online conversation taking place on a particular blog post, forum thread or Facebook wall post.
Hey, I know you simply wanted to show your affection by commenting on my wall or blog post, but you have clearly missed the entire point and your comment was effectively the stopping block of what could've been an engaging online conversation with social peers. You just made a Lasties.
